Air cleaner

Abstract

An air cleaner according to an embodiment of the present invention comprises a housing including a suction portion through which external air is suctioned and a discharge portion through which the suctioned air is discharged; a filter disposed between the suction portion and the discharge portion and configured to purify the suctioned air; a gas pump connected with the discharge portion and configured to rotate so as to discharge the air purified by the filter to the discharge portion and a controller configured to control a rotation direction of the gas pump, wherein the gas pump includes a rotor including a gas pump base disk disposed in and rotatably supported by the housing, a gas pump disk array in which segment disks having an open center area are disposed on the gas pump base disk to be spaced apart from each other, and a rotor magnet installed on the gas pump base disk and a stator including a stator coil disposed in the housing and installed to face the rotor magnet.

AI Technical Summary

Benefits of technology

The present invention is an air cleaner that can purify and circulate air without generating a lot of noise.

Problems solved by technology

All conventional commercialized air cleaners and dehumidifiers circulate air using a method of a rotating Sikorsky or propeller, and thus noise generated when a Sikorsky blade or a propeller blade collides with air is unavoidable.

Since some dehumidifiers do not have an air circulation function to avoid generation of noise but do not forcibly circulate humidity in the air, dehumidification efficiency is too low, and thus commercialization of most of such dehumidifiers have failed.

Further, some heating-type humidifiers do not include an air blower but have very low humidification efficiency, and an ultrasonic humidifier that essentially requires an air blower has a serious problem of generating an air blowing noise.
